I have installed the DSS on several platforms for comparison and am seeing something strange happening on the version that is running on linux. I noticed that the stream dies periodically. In VLC the stream simply hangs. In quicktime, the stream dies briefly, then you see quicktime establish a new rtsp connection and the stream picks up where it left off.
We attached a debugger to the process and this is what we saw:
Program received signal SIGFPE, Arithmetic exception.

delta = 999
theTime = 0
bits = 0
numProcessors = Variable "numProcessors" is not available.
Now I looked at the code and I am not sure what is happening (I am not a C++ programmer) but if delta is less than zero then the following line will cause theTime to be equal to 0:
UInt32 theTime = delta / 1000;
If theTime equals 0 then line 423 will fail everytime:
packetsPerSecond /= theTime;
The following code inplies you are aware of the problem but other than the warning no excpetion handling occurs:
if (delta < 1000)
WarnV(delta >= 1000, "Timer is off");
Am I reading this right or is their another reason why the code might be failing at this line?
Thanks for your help.
Sincerely,
Daniel Wells
